Abstract
A containment flap for an absorbent article, such as an incontinence garment, has elasticity in the long axis and extensibility of the flap with a low modulus of elasticity in its transverse direction. The long axis tension of the flap has a force vector normalized to the transverse direction when the flap is placed in curvature over the body of a wearer, thereby providing a force for extending the flap in the transverse direction to maintain contact with the body of the wearer when the garment begins to sag, such as may happen due to gravity when the garment is loaded with absorbed bodily fluids. Material suitable for constructing such flaps is further disclosed.
Description
Technical background
Trousers shape moisture absorption clothes such as diaper (trousers) and training pants comprise a pair of trouser legs mouth and a waist mouth usually, and this trouser legs mouth has around the elastic part of each trouser legs mouth, and this waist mouth also has elastic part.This elastic part is that the leg that is used for fitting tightly around the wearer leaks out outside these clothes with the refuse that prevents health, and refuse this paper of this health is also referred to as " exudate " sometimes, is to continue often to exist and leak.
Once taked some diverse ways to reduce or eliminate the leakage of moisture absorption clothes.For example, the physical barriers layer such as the force-loose leak resistant vane just once was bonded in this moisture absorption clothes.Normal generation liquid at the moisture absorption clothes emits the quantity and the shape of the hygroscopic material in the zone (being sometimes referred to as the target area) of gushing also to have change.
Another method that reduces the exudate leakage is the tension force that increases around the elastic part of each trouser legs mouth and waist mouth.The tension force of this increase usually is effectively, but often causes a kind of undesirable red seal note on wearer's skin, and this red seal note is owing to increased pressure on wearer's skin causes.
In the past, once some was restricted in the use of leak resistant vane, because this fin has limited width at its transverse direction, mean when these moisture absorption clothes become the refuse of the health that is loaded with absorption sagging or fall because of gravity, this liner will be pulled away from wearer's health, be sometimes referred to as " losing vertical applying ", caused a kind of undesirable leakage path that leads to this outside of clothes thus.Technical known provide " oversized dimensions " liner to test and adapt to sagging scope, but caused from increase economic and that the undesirable fabric of comfortable two aspect viewpoints uses.
A kind of demand or hope to the horizontal extensible material that is applicable to the liner done in the moisture absorption clothes or leak resistant vane is arranged, and this liner or leak resistant vane are sealed in liquid in these moisture absorption clothes and according to the degree of sag that the clothes of refuse are housed and regulate on transverse direction to keep sealing.

Seen in Fig. 4-6, clothes 2 according to the present invention will have fin 50, hereinafter will describe singularization, and it extends on corresponding to long axis of the longitudinal axis of clothes 2 or direction 62 or direction.Fin 50 will have: what linked one links edge 52, promptly be installed on these clothes or with this clothes all-in-one-piece edge; One free edge 64 (Fig. 5 and 6) of contact wearer 5 healths.Fin 50 will have the transverse direction 66 perpendicular to its length direction 62.Arrow 68 indication long axis tension force σ
1, this tension force σ
1Be to realize by the rectangular upwardly extending elastic cord 70 that is attached to fin 50.
As seen in Figure 5, liner 50 greatly extends perpendicularly to clothes framework 3 on its position of function, has constituted all parts of this disposable absorbent article except that this fin 50 with framework 3 for this purpose.The part 65 expressions extension with dashed lines of this liner or imaginary.Elastic component 70 or elasticity can be as discussed above or be provided in any known mode, and this mode is enough to cause the power of normal direction, and this normal force is enough to make this fin to extend on transverse direction 66.
The material that is suitable for constructing according to liner of the present invention will satisfy standard, this standard is: extending easily on the first direction and having low recovery or modulus of elasticity and for example hold Lycra (trade mark) filamental thread easily or as discussed abovely produce a tension force on perpendicular to the second direction of first direction.This material also should provide suitable liquid barrier property to play liner.Wish to have soft hand feeling and other aesthetic property in addition.Each material that expection is used spunbond/meltblown/spunbonded (SMS) laminated multi-layer product, spunbond non-WEB and the film/non-of spinning spin the microporous membrane/nonwoven webs laminate that comprises the neck expansion among the WEB lamination product, such as can be at common pending application series No.60/201, find in 830 and below further discuss.Really many materials of enumerating or their part material can be during their manufacturing suitable neck expansion on machine direction, on their direction of traversing machine, cause ductility thus, this direction of traversing machine finally becomes the transverse direction of this fin.The film that satisfies above standard also can use separately or also can use jointly with the nonwoven webs of crimped fibre.Height-oriented nonwoven such as the netted thing of bonded carded of certain form also can be applicable in the scope of the invention.
With particular reference to Fig. 6, can see moisture absorption clothes 2, when becoming the liquid that is loaded with absorption, will be at the sagging health of gravity 77 effects from wearer 5.Vertically be fitted in common generation of this forfeiture and cause the liner 50 of leakage and the gap 79 between the wearer 5.But by the measure of fin 50 of the present invention, when clothes 2 were sagging, fin 50 extended so that keep and the contacting of health 5 towards health 50 as line 81 is indicated, and the leakage that seals and prevent to lead to this outside of clothes is provided thus.
With reference to figure 7, part 54 extensions of outer cover 48 exceed moisture absorption layer 44 in one embodiment, and the part 54 of this extension can play seamless leakproof effect.So-called " seamless ", its meaning is: this leakage preventive portion be not link separately and therefore do not need to be linked to this refuse and press down a seam that leaks part 4.Be leakproof effectively, the difference of the width between moisture absorption layer and the outer cover must be basic within the middle section between the trouser legs mouth 15.Usually, this outer cover 48 is wideer by about 40% than this moisture absorption layer 44 at least at this middle section 15.What conform with demand is that this outer cover is wideer by about 40% than the moisture absorption layer in the middle section 15 44 at least.This outer cover 48 in the present embodiment will be like this with regard to this liner by containing elastic cord 70, constructing and arrange according to the material of normative choice discussed above at least.
With reference to figure 8-12, shown an alternative embodiment of the invention.This embodiment comprises the liner 150 of structure to make fin shape of non-woven and flexible material, liner 150 the longitudinal direction of disposable absorbent article 2 work and its in have folded part 148.This configurations of tabs comprises: a horizontal ductile surface lining, and some low tensile elasticity lines 152 are adjacent with skin to keep fin 150, and some higher tensile elasticity lines 154 contact with user's the close of body surface 5 with maintenance to promote configurations of tabs.
With reference to figure 9 and 10, liner 150 is configured to: the clothing department between higher tensile elasticity line 154 and this clothes divides lateral surface 156 its ends 160,162 to be bonded on the clothes framework 3.Equally, the end of the medial surface 158 of liner 150 links each other.
Between the longitudinal end of clothes framework, liner 150 only is that its binding edge 164 is linked to this framework, and the interior and outside 166,168 that stays this liner respectively moves freely.Contain than the line 152 of low-tension during life of product whole, to contact with each other with wearer's health 5 continuously allowing the zone of the lax edge of this fin at the elastic properties of materials on the transverse direction between clothes 2 and the higher tensile elasticity line 148.
Ductile gasket material needs low-down elastic modelling quantity on transverse direction.High tensions elastic cord 154 must have the enough tangential forces towards user's health 5 surfaces, and generating a normal force on the transverse direction of configurations of tabs, this normal force can make this gasket material easily extend breakaway poing until it from 0% elongation.The extensibility that liner is constructed this part makes the liner free section between higher tensile elasticity and lax edge divide maintenance to abut in reliably on the body surface 5.Low rate of tension line 152 also provides ductility and the comfortableness along user's body surface.
